It’s one thing to run a friend through a dungeon that might be a little too rough for them because you’re a Cool Pal. It’s something else entirely to do it for a rando and ask for real money in return. In World of Warcraft, the latter is unacceptable, and Blizzard’s started banning top players for it.

According to PCGamesN, it’s become fairly commonplace for the cream of the game’s crop to boost players with less time (but more money) on their hands through tough dungeons. The boost-ee gets loot and achievements, and the boost-er gets real cash. Everybody wins... sorta. Blizzard, however, says they’re done turning a blind eye to these practices.

“We’ve recently taken action against a number of accounts that were actively participating in and/or advertising the sale of in-game raid or dungeon clears in exchange for real-world currency,” community manager Bret “Ornyx” Forbus wrote in a forum post. “Such behavior is a clear violation of the World of Warcraft Terms of Use.”

“Of the players affected, many were members of top raiding guilds,” he added. “We want to be clear that everyone we’ve taken action against had illustrated full knowledge and intent to violate the Terms of Use. Going forward, in order to ensure fair play and competitive integrity, we’ll be monitoring these activities much more closely in order to make sure that the rules are being followed. This includes selling services for real money, account-sharing, and other violations.”
